Disease relevance of EBP

 

Psychiatry related information on EBP

  • Furthermore, the 3T C/EBP site I was not found in brain-derived LTRs of patients without HIV-1-associated dementia (HIVD), but was found in increasing numbers in brain-derived LTRs from patients diagnosed with HIVD [5].
  • As the field continues to mature, energized by the challenges to develop treatment in more innovative ways and to disseminate EBP, the potential for improving child mental health is strong [6].
  • Enhancing the EBP repertoire of substance abuse counselors: A commentary on Kerwin, Walker-Smith, and Kirby [7].
 

High impact information on EBP

  • C/EBP-related transcription factors regulate the balance between cell proliferation and mitotic growth arrest during terminal differentiation [8].
  • Using SSCP analysis and sequencing of genomic DNA, we found EBP mutations in all probands [1].
  • The phenotype in CDPX2 females ranges from stillborn to mildly affected individuals identified in adulthood [1].
  • Our results indicate that defects in sterol-delta8-isomerase cause CDPX2 and suggest a role for sterols in bone development [1].

Associations of EBP with chemical compounds

 

Physical interactions of EBP

  • We conclude that c-Rel((1-300)) binding to C/EBPbeta increases the affinity of C/EBPbeta for the C/EBP binding site at -53 on the CRP promoter, and that the transactivation domain of c-Rel is not necessary for this effect, which depends on protein: protein contacts with C/EBPbeta [25].
 

Other interactions of EBP

  • Nine out of ten amino acid residues essential for catalytic activity of EBP were conserved in EBPL [15].
  • Indeed, while competitive experiments indicated that EBP prevails in mediating SR31747A antiproliferative activity, an analysis of the expression of both receptors indicated that the cellular sensitivity to SR31747A is not correlated with either EBP or SR-BP expression [26].
  • Inhibition of Tax-mediated transactivation of the HTLV-1 LTR was co-activator-independent, did not require C/EBP binding to the Tax-responsive elements, and may involve heterodimerization with CREB factors [2].
  • These findings were strikingly similar to the IL-6 promoter, where IL-17-mediated regulation of both NF-kappaB and C/EBP is essential [27].
  • The C/EBP homologous protein CHOP (GADD153) is an inhibitor of Wnt/TCF signals [28].
